Abstract

The invention relates to a method and a system for snapping photos of vehicles overspeed. The method includes: acquiring multiple sets of ranging data in the scanning plane received by the laser ranging unit; acquiring the vehicle-filled area in the scanning plane according to any set of ranging data; Calculating the number of vehicles contained in the car-filled area and the lane to which each vehicle belongs within the preset range; calculating the driving speed of each vehicle according to any two sets of ranging data; comparing the driving speed of each vehicle with the speed threshold , when the speed of the vehicle exceeds the speed threshold, trigger the capture unit to capture the vehicle image information of the speeding vehicle. The vehicle speeding capture system provided by the present invention is used to realize the above method. The invention can identify the speed of the vehicle in the scanning plane, especially can detect the overspeed situation of the vehicle under the condition of paralleling the vehicle, and improve the detection accuracy. The system provided by the invention is convenient to carry and improves the scope of application.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and a system for capturing a vehicle overspeed. Background technique [0002] With the rapid increase in the number of motor vehicles, many traffic problems and safety hazards have been brought. Wherein, motor vehicle speeding is one of the main causes of traffic problems, in order to curb this type of incident, there have been multiple motor vehicle speed detection devices in the prior art. [0003] The above-mentioned vehicle speed detection device includes a speed measurement device based on video, a speed measurement device based on ground induction coil, a radar speed measurement device based on Doppler principle and a laser speed measurement device based on laser Doppler effect. Among them, the video-based speed measurement device has relatively large errors and has been gradually eliminated. The speed measurement device based on the ground sen...
